UNITED STATES PATENT OFFICE JOSEPH TRENT, OF NEW YORK, N. Y., ASSIGNOR TO THE MANHATTAN I BURNER COMPANY, OF SAME PLACE. v I

IMPROVEMENT IN CONES FOR LAMP-BURNERS.

Specification forming part of Letters Patent No. 216,540, dated June 17, 1879; application filed April 3, 1879.

To all whom it may concern:

Be it known that I, JOSEPH TRENT, of New York city, in the county and State of New York, have invented a certain new and useful Improvement in Cones for Lamp Burners, which improvement is fully set forth in the following specification and accompanying drawings, in Which- Figure l is a top View, and Fig. 2 is a vertical section, of my improved cone.

My invention consists in applying a bushing or lining around the edge of the opening through which the flame passes.

The object of my invention is to give a smooth edge to the flame-opening; and my invention is more especially adapted to glass cones, as such cones are very apt to have rough edges, particularly after having been a little used.

lined or hushed and entirely protected from contact with the flame, substantially as and for the purpose set forth.
